I just migrated my cards over to a new Asrock B450 Pro4 and Athlon 3000G APU coming from a Z170 Intel platform. Everything booted up fine and works great but I noticed that my onboard video is disabled. When I boot the rig I can get into BIOS and it shows the initial HiveOS blue boot screen but once it loads the OS everything goes black. I’d like to keep the onboard video output working as I have a monitor for local display and troubleshooting. I’d prefer not to plug into a dedicated GPU for this. On the HiveOS page it says the Picasso AMD/ATI device is disabled.
In BIOS I have iGPU forced on and dedicated 2G of memory to it. I’m currently running UEFI with CSM disabled. I’ve read mixed success stories about running legacy with MBR. I might try loading an install on a flash drive to see if this helps. Any thoughts?
